Example: Create a Chart with a Time Axis

This example shows how to create a Chart with a Time Axis.

When plotting data across a range of dates, it's sometimes preferred to use TimeAxis instead of a CategoryAxis. While a CategoryAxis plots ticks on an axis for each data point on a graph, a TimeAxis plots ticks evenly across a time range. A TimeAxis can be applied to a Chart by setting its categoryType attribute to "time".

CSS

#mychart {
    margin:10px 10px 10px 10px;
    width:90%;
    max-width: 800px;
    height:400px;
}

HTML

<div id="mychart"></div>

JavaScript

var myDataValues = [ 
    {date:"1/1/2010", miscellaneous:2000, expenses:3700, revenue:2200}, 
    {date:"2/1/2010", miscellaneous:50, expenses:9100, revenue:100}, 
    {date:"3/1/2010", miscellaneous:400, expenses:1100, revenue:1500},
